A bit more formal than a standard-issue t-shirt, the ultra-cotton long sleeve tee is a clear comfort winner. The sleeves also act as a nice frame. There are no side seams. The shoulders are taped for improved durability. This makes for a good fitting around the shoulders and neck. The cotton used for these shirts is environmentally friendly.
